Why my Yamaha Amplifier fails to turn on?

  Kimberly RobbinsAug 18, 2025
  If your Yamaha Amplifier fails to turn on, ensure the power cable is firmly connected. Also, check that the A (power) switch on the front panel is on, especially if you were using the remote control. The issue might also stem from the impedance setting of your connected speaker; make sure it's appropriate. If the speaker wires are touching, causing a short circuit, correct their placement. If none of these steps work, it could indicate an internal problem, requiring you to disconnect the power cable and contact an authorized Yamaha dealer or service center.
